TOBACCO-PIPE.

Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed February 17, 1911. Serial No. 609,091.

To (LZZ whom it may concern:

Be it known that I, EUGENE GILBERT, a citizen of the United States,residing at Gladstone, in the county of Delta and State of Michigan,have invented a new and useful Tobacco-Pipe, of which the following is aspecification.

It is the object of this invent-ion to provide a smoking pipe soconstructed that the saliva will be prevented from finding its way intothe bowl of the pipe, the material resulting from the burning, anddestructive distillation of the tobacco, in the bowl of the pipe, beingprevented from finding its way into the mouth of the user of the pipe.

I/Vith the foregoing and other objects in View which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings,-Figure 1 is a longitudinal section, wherein sundrydetails appear in elevation; Fig. 2 is a transverse section on the lineA-B of Fig. 1; Fig. 3 is a perspective of the primary tube and theelement whereby the same is immediately carried; and Fig. 4 is aperspective of the secondary tube, together with its carrying element.

In carrying out the invention there is provided a tubular casing 1, intothe upper end of which is inserted a plug 2, having a reduced neck 3adapted to register closely in the bore of the casing 1, the neck 8 ofthe plug carrying a primary tube 4, extended downwardly within thecasing 1, to a point adjacent the bottom of the casing. The pipe stem 5is secured in the plug 2 by threading, or in any other desired manner,the construction being such that there is a continuous opening throughthe pipe stem, and through the primary tube 4.

The bore of the casing 1 is enlarged at its lower end, to form a chamber6, into which is inserted the neck 7 of a cap 8, the neck 7 carrying asecondary tube 9 extended upwardly to a point adjacent the bottom of theplug 2, the secondary tube 9 inclosing the primary tube 4, the tubesbeing spaced from each other, and the secondary tube 9 being spaced fromthe adjacent wall of the casing 1. The cap 8 may be chambered out, toany desired extent, as shown at 10, below the secondary tube 9.

Adjacent its lower end, the casing 1 is equipped with a circumscribingrib 11, into which is inserted a short stem 12, communicating at one endwith the bore of the casing 1. The outer end of the stem 12 is extendedthrough the side wall of the bowl 14 of the pipe, there being a plug 15in the bowl 14, positioned above the intake end of the stem 12. In theplug 15 there is an opening, through which is inserted a short dependingtube 16, extended downwardly to a point adj acent the bottom of the bowl14. A removable, closure cap 17 is fitted over the lower end of the bowl14. As the tobacco burns in the bowl 14, the nicotin, passing downwardlythrough the tube 16, will find lodgment in the cap 17, which cap mayreadily be removed, to permit the nicotin to be poured off. The smokewill pass downwardly through the tube 16, and thence upwardly around thelower end of the tube 16, through the member 12. Should any condensationtake place in the member 12, the condensate will find lodgment upon thetop of the neck 7 of the cap 8, below the inner end of the member 12,the condensate being thus prevented from being drawn upwardly into andthrough the stem 5 of the pipe. The smoke, having entered the bore ofthe casing 1, through the member 12, will pass upwardly between theinner wall of the casing l and the secondary tube 9, over the upper endof the secondary tube 9, thence downwardly between the secondary tube 9and the primary tube 4, thence upwardly through the primary tube 4 intoand through the stem 5. The saliva and moisture, accumulating in thestem 5 and in the primary tube 4, will flow downwardly into the chamber10 in the cap 8, the cap 8 being'freely removable, together with thesecondary tube 9, to permit the accumulations in the chamber 10 to bedrained away, when the secondary tube 9 and the cap 8 are inverted.

From the. foregoing it will be seen that the objectionable materialresulting from a burning of the tobacco, will accumulate in the cap 17the saliva and moisture traversing the primary tube 4, accumulating inthe chamber 10 of the cap 8. It is obvious therefore, that the nicotinand other products resulting from the burning of the tobacco, cannotfind their way into the mouth of the user, nor can the saliva andmoisture find its way from the mouth of the user into the bowl 14 of thepipe. Owing to the factthat the smoke is forced to travel in a sinuouspath through the tubes 4 and 9, the smoke will be thoroughly cooledbefore it is received into the mouth of the user of the pipe.

Having thus described the invention, what.

is claimed is In a device of the class described, a stem comprising atubular casing; a closure for the lower end of the easing,'having asaliva chamber; an outer tube within the casing and terminally mountedin the closure, the outer tube communicating with the chamber, theclosure being otherwiseimperforate in its upper face; a closure for theupper end of the casing, adapted to receive the mouth piece; an innertube in the last named closure, located Within the outer tube andcommunicating with the chamber, below the outer tube; there being anopening in the side of the casing, adapted to receive bowlholding means,the opening being spaced above the upper face of the first namedclosure, to provide for an accumulation of liquid material from thebowl, upon the upper face of the first mentioned closure.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two Witnesses.

EUGENE GILBERT.
